📖 Overview
Recreate the exact stick feel when moving between different flight controllers or firmware versions. This tool models rate curves mathematically to convert stick sensitivity and maximum deg/s rotation rates across Actual, Betaflight, Quick, KISS, and RaceFlight algorithms.
🛠️ How to Use
Set your active rate values using the sliders or numerical inputs for Roll, Pitch, and Yaw.
Choose your source rate system (e.g. Betaflight) and your target rate system (e.g. Actual or KISS) from the dropdown selectors.
Click Convert to run a hybrid grid search algorithm that automatically finds the mathematically closest rates for your target firmware.
📊 Understanding the Charts & Controls
Rate Curve View: Overlays your source curve against the target curve, showing rotation speed (deg/s) from 0% center to 100% full stick deflection.
Center Zoom Button: Zooms into the 0%–25% stick deflection zone for ultra-fine inspection of micro-corrections around center stick.
Sensitivity Tab: Plots rate curve derivative slope (deg/s per mm of stick travel), giving you an exact mathematical visual of how linear or exponential the center stick response feels.
